DescribeInstanceMonitorData - Elastic Compute Service - Alibaba Cloud Documentation Center

Queries the monitoring data of an Elastic Compute Service (ECS) instance. The monitoring data can include the vCPU utilization, CPU credits of the burstable instance, amount of received data traffic, amount of sent data traffic, and average bandwidth.

Operation description

Usage notes

Take note of the following items:

Up to 400 monitoring data entries can be returned at a time. Make sure that the TotalCount value does not exceed 400. The value is calculated by using the following formula: TotalCount = (EndTime - StartTime)/Period. If the TotalCount value is greater than 400, the InvalidParameter.TooManyDataQueried error is returned.
You can query the monitoring data in the last 30 days. If the value of StartTime is more than 30 days earlier than the current time, an error is returned.
In some scenarios, such as when the instance is in the Stopped state, the system cannot obtain the relevant information and specific information may be missing from the returned monitoring data.
You cannot call this operation to obtain the CPU basic monitoring information of an ECS bare metal instance. To obtain the CPU monitoring information of an ECS bare metal instance, install the CloudMonitor agent on the instance. For more information, see InstallCloudMonitor .

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer.

Request parameters

Parameter	Type	Required	Description	Example
InstanceId	string	Yes	The instance ID.	i-bp1a36962lrhj4ab****
StartTime	string	Yes	The beginning of the time range to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. If the value of seconds (`ss`) is not `00`, the time is rounded up to the next minute.	2014-10-29T23:00:00Z
EndTime	string	Yes	The end of the time range to query. Specify the time in the ISO 8601 standard in the yyyy-MM-ddTHH:mm:ssZ format. The time must be in UTC. If the value of seconds (`ss`) is not `00`, the time is rounded up to the next minute.	2014-10-30T08:00:00Z
Period	integer	No	The interval at which to retrieve monitoring data. Unit: seconds. Valid values: 60 600 3600 Default value: 60.	60
